The B875–200 configurable A/D input module converts a variety of signal sources: thermocouple, RTD, strain gauge/load cell, voltage and current input ranges into binary data. When selected for eight channels, the module is displayed in the I/O map as a B875–200; when selected for four channels, it is displayed in the I/O map as a B873-200.
The module provides the capability to poll a wide array of field devices requiring different signal sources based upon the application selected. Selection may be made from more than 48 available input packs, with any mix per module being acceptable.
NOTE: Third-party input packs
Performance is not guaranteed with third-party 5B type packs. When using third-party packs, contact the manufacturer for support.
An eight-position DIP switch is used to select from one to eight input channels per module. In addition, a two-position jumper is used to select either 0, 2, or 4 samples to be averaged per input. Averaging helps reduce the impact of spurious noise on the input.
Some application examples include food processing, press operating, chemical processing, painting, and foundry casting.
The module has four/eight analog inputs and is capable of updates to all eight channels every 4 ms. The 12-bit resolution for all ranges, and the absolute accuracy is dependent on the input pack type. This allows for fast and precise control of the application.
NOTE: This module requires two slots.
